Convert PHP script so it can run on a node.js site

Our website is built in node.js and hosted on Heroku. We have used Ecwid to drop a shopping cart into the site. [login to view URL] is an ajax driven product built so you just insert one line into your HTML and you have a shopping cart. The problem is that search engines do not properly index the products for sale in ecwid out of the box because it is ajax. So a little extra works needs to be done so that the SEO functions correctly. This is where you come in. Ecwid provides clear instructions for setting up a script to insert into the same webpage as the ecwid shopping cart to generate the required SEO. Unfortunately these instructions are only for a PHP site. A PHP script is provided which I need converted into something that can run on our node.js / heroku site. Here are the instuctions from ecwid for what it is that we are trying to do: [login to view URL] Here is the 700 line script ([login to view URL]) that I would need converted from PHP to be able to run on our site: [login to view URL] A big part of this job is not just coding the script so it can be placed on our ecwid product page, but also testing and proving that the script is working as expected. There are also test instructions on the ecwid portal link outlined above. Finally we need to confirm that google is actually indexing a product as expected. We can submit a page to their index through webmaster tools to confirm the indexing is correct. Please note I will not respond to replies that are asking for more money than the specified budget.
